WINDING-MACHINE.

Specification of Letters Patent.

Patented Feb. 17, 1914.

Application filed July 5, 1912. Serial No. 707,824.

To all whom it may concern Be it known that we,'ARTHUR I. H RVEY and.VVILLIAM MAnonor'r, citizens of the United States, residing at-Providence and .chine to wind several layers of yarn on the bobbin with.a relatively short traverse before the winding of the main port-ion ofthe bobbin with the maximumtraverse is commenced.

The object of our improvement is to provide a machine having abunch-building attachment for performing the bunch winding at thebeginning of the bobbin, the term bunch being generally used todesignate the short section of yarn first wound on the naked bobbin anddesigned to cooperate with the feeler-dcvices which control the weft orfilling-replenishing mechanism of automatic looms.

The invention is fully described in ,the

following specification illustrated by the accompanying drawings, inwhich Figure 1 is a longitudinal'elevation of a winding machine showingour new device applied thereto, the main frame of the machine beingillustrated in section to disclose the operating mechanism containedtherein; Fig. 2,21- plan view of the same; Fig. 3, a detail view of aportion. of the stopping mechanism of the machine; Figs. 4, 5, 6 and 7,enlarged detail views of the controlling device for thetraverse-mechanism, illustrating the parts in progressive stages oftheir operation; Figs. 8, 9 and 10, detail views of the parts of thecontrolling device.

()ur invention is shown as applied to a machine of the same general typeas that described in U. S. Patents Nos. 940,489 and 946,831, grantedNov. 16,1909, and Jan. 18,

1919, respectively, to S. W. lVardwell. The basic machine consistsessentially of a rotating winding-spindle B and a reciprocatmgtraverse-bar C, the latter arranged opposite the spindle, and adapted tocarry the thread-guide G, which besides its movement with the bar isfedprogressively outward thereon to build the cop in superimposedconical layers. The winding-sp1ndle B is mounted in a bearing a in themain frame A of the machine and is rotated from the main driving-shaft Eby means 'of skew-gears e, e. The traverse-bar C slides in a quillshapedbearing a, which has an extension a extending through a bore in'the sideof the frame A, and is reciprocated from a rocker-arm F mounted on thecontinuouslyoscillated shaft D. Our new traverse-controlling deviceoperates directly in connection with the arm F and is arranged toautomatically adjust the point of connection of the traverse-bar C withthe arm to vary the operative length of the latter and regulate thelength of traverse of the thread-guide.

as niore fully explained hereinafter. v

. The traverse-bar C is preferably constructed in two parts C and C themain portion C sliding in the bearing a, as before explained, and theextension C con nected thereto at its outer end by a pin-andslotcoupling a. The outer end of the extension C is mounted in a bushing 0which is swiveled in an outboard bearing 7' supported on a bracket Jextending from the frame A. The coupling 0 allows the inner end of theextension C to swing inward from the plane of the axis of the mainportion C of the bar, as shown in Fig. 2, while the outer end of the barswings in the swiveled bushing o. This arrangement is the same as thatdescribed in U. S. Patent 940,489, above referred to, and provides thatthe contact means carried on the traverse-bar, and ar ranged to feed thethread-guide along the winding-spindle, shall contact with the firstlayers of yarn wound on the bobbin a: before the base of the cop isbuilt up to its maximum diameter. The progression or contact-mechanismis arranged as now briefly described, a more comprehensive descriptionbeing given in the patent just referred to.

l jlit The thread-guide G is preferably supported on a thread-guideholder or arm g, of bifurcated form, having two legs 9, g terminating inbearings 9 g surroundingthe 5 bar C Between the bearings 9 g is aninternally threaded sleeve or nuth which carries a relatively thin diskH called the contact-wheel. The bar C is formed with screw-threads 0extending approximately 10 half way around its circumference and aspring h is secured to the guide-holder g with its end bearing on aflange h of the nut 71.. The spring it acts to normally press the nut itinto position to engage its threads with the threads 0 on the bar 0*,but the bore of the nut is of sufficient diameter to allow its threadsto pass over those on the bar when the nut is pressed in the oppositedirection against the force of the spring. It

will be seenthatwhile the machine is operating the nut h is engaged withthe threads on the bar C so that the turning of the wheel H will feedthe thread-guide along the winding-spindle, but by releasing the nutfrom engagement with the threads on the bar the guide can he slid backto adjust it in position to begin the winding of a new bobbin.

Mounted on the end of the bar C is a former K, so termed because itactsto direct the movement of the contact-wheel H away from thewinding-spindle during the building of the base or heel'of the bobbinand therefore determines the form of the latter. The former K has an armis arranged with its edge is at an angle to the axis of thewinding-spindle and by adjusting the armat different angles the taper ofthe base of the bobbin can be regulated.

40 Adapted to bear on the edge 70' of the arm A: is a follower-arm gextending rearwardly from the thread-guide holder 9. Sliding in a boreat the inner end of the bar C is a spring-pressed plunger 0 adapted tobear against the inclined face 0 of the couplingplate a and tending tonormally hold the bar C in position to aline its axis with that of thebar C. The swinging movement of the bar C is limited by its pin 0sliding in the slot 0 of the plate a and with the follower 9 bearin onthe former-arm k the end of the bar is held with the pin at the innerend of the slot as shown in Fig. 2. This provides that the contact-wheelH will be maintained in close proximity to the surface of the bobbin orcop-tube at the beginning of the windin so that its periphery willcontact with t e first layers of yarn wound on the latter at therearward end of each stroke of the thread-guide. The contact of thewheel with the surface of the yarn, during the rotation of thewindingspindle, acts to turn the wheel to feed the thread-guide outwardalong the spindle in the manner now well known to those versed oewe? inthe art. As the thread-guide feeds outward along the traverse-bar C thefollowerarm g slides along the incline of the arm is and allows thecontact-wheel to recede from the axis of the winding-spindle inaccordance with the growth in diameter of the winding. As the follower 9reaches the end of the arm I: the base of the bobbin or cop attains itsmaximum diameter and. the bar 0 assumes a position in alinement with thebar C. Henceforth the two sections C and C of the traverse-bar C arereciprocated in the same plane, as one continuous bar, and thecontact-wheel H engages the bobbin at the rearward end of eachreciprocation at a point on the base of its forward conical end. In thisway the bobbin grows by longitudinal extension, the conical layersforming a substantially cylindrical body terminating in the tapereddelivery end or nose.

The stopping-mechanism of the machine for arresting the rotation of thewindingspindle and the reciprocation of the threadguide consistsessentially of a rockable bridge-member L which is pivoted on suitablehearings in the frame A and extends across and above the shafts E and D.The inner end of the member L is mounted on a rod Z secured in the innerside of the frame A and the outer end is formed with a socket Z whichreceives the end of an extension L secured in place by the screw Z Theextension L reaches through a bearing in the outer side of the frame A,and secured in a bore at its end is a rod M held by the setscrew m. Theopposite end of the rod M passes through a bearing m in the bracket Jand is bent down to form a handle M.

The skewgear e which is driven from the gear e is'mounted free to turnon the winding-spindle B and is connected rotatively therewith by meansof a clutch-member N, see Figs. 1 and 2. The clutch-member N is keyedrotatively with the spindle, but is free to slide thereon to carry itstapered face a into and out of engagement with the corresponding face 6of the gear 6. A coiled spring n bearing against a collar n tends tonormally maintain the clutch-member N in engagement with the gear 6sothat the winding-spindle is driven therefrom; and the clutch-member isre; leased from the gear a to arrest the rotation ,of the spindle bymeans of a'lei'er Z The lever Z is preferably formed as a part of thebridge-member L and extends upwardly therefrom with its end adapted toengage the beveled face of an annular flange a formed on. theclutch-member N.

Referring to Figs. 2 and 3, the rockerarm F which reciprocates thetraverse-bar C is formed with a double hub f mounted free on the shaft Dand connected therewith by a clutch-bloek O secured on the shaft by ascrew 0. Preferably, the hub f is provided 1 block.

with a key or spline 1'' adapted to engage a corresponding slot 0 in theface of the block 0 and a coiled spring 0 bearing againstv acollar 0tends to normally hold the hub f in engagement with the clutch Thehub .fis disengaged from the block 0 by means of the bridge-member L which isformed with an overhanging portion Z having aface Z adapted to engagewith a tapered projection f on theend of the hub f to slide thehubagainst the action of the spring 0 see Fig. 3. A double-ended springZ, see Figs. land 2, is secured to the top of the member L with its freeends Z Z reaching down adjacent the sides of the projection f on the hubf of the arm F. The

ends of'the spring Z act to prevent excessive rocking movement of thearm F after its disengagement from the clutch-block O and serve toholdthe arm in such relation to the clutch-block as to insure the splinef" being engaged with the slot 0' upon the release of the hub from themember L.

Referring now to Figs. 4, 5, 6 and 7, the arm F is formed with a curvedslot f extending from its upper end to a point adjacent its hub.Connected to the main por-n tion .0 of the traverse-bar C by a pin 0" isa link P. carrying a. stud at its opposite end adapted to engage theslotF. A coiled spring 9 fastened to an extension f on the top of the arm Fand secured to the link P at 79' tends to normally maintain the stud pat the upper end of the slot f see Fig. 7. By sliding the stud 72 downin the slot f the operative effect of the arm F maybe varied to shortenthe extent of traverse imparted to the traverse-bar C and throughthelatter to the thread-guide G. At the commencement of the winding of abobbin the stud is held p at the lower end of the slot f and willtherefore move through an arcof relatively short radius when the arm Fis'oscillated, so that the thread-guide is reciprocated with arelativelyshort traverse to build the bunch on the bobbin." When the bunch hasbeen builtup to the required diameter, or, more properly speaking, whena sufficient length of yarn has been wound into the, bunch, the stud 12is'moved to the upper end of the slot f and the traversebar C will thenbe reciprocated with the mariimum extent of. traverse to wind the fulllayers whichform the mainportion of the bobbin. The means forautomatically controlling the position of the stud 79 in the slot P willnow be described.

Pivoted on a screw 0* screwed into the side of the arm F is a ratchetdisk or wheel P R having an annular rim or flange r on its smallerdiameter than its main portion to adapt it to enter the opening 1 in theflange hen the disk is 'turned to register the opening r with the slot fin the arm- F, as shown in Fig. 4, the pin 29? will pass through theopening 7' and by turning the disk slightly the under side of the flange1" will engage the in and retain the stud p at the lower en of the slotJ, as illustrated in Fig. 5; To release the pin p fromflengagement withthe flange?" the disk R" rotated in the direction. indicated'bythe'arrow z, Figs. 4, 5, 6 and 7 until the slot- 1' again registers withthe slot f in the arm F. This rotation of the disk R takes place duringthe winding-of the bunch onthe bobbin and is effected by the rockingmotion of the arm F through means now described: Secured to the hub f ofthe arm F by a screw 8 is a flat-spring pawl S formed with a hooked end8 adapted to engage the teeth r on the ratchet-disk R to preventmovement of the latter in' a direction opposite to that indicated by thearrow 2. Pivoted on a stud t adjacent the end of the link P is a pawl Tformed with a hooked end t,

also adapted to engage the teeth 1 on the disk R. The hub ofthe pawl Tis formed with a lug or abutment t havinga flat face t see Fig. 10,against. which the end of a spring U-bears. The spring U is preferablyformed of flat spring-metal, bent in hairpin shape, and secured inposition bya 'pin '0' held in the end of the link P and having aslot 42through which one end at of the spring passes. The tendency of thespring U is to hold the pawl T in the position illustrated in Fig. 6 toadaptits end to engage the teeth 1 on the disk R, while allowing the awlto rock slightly to ride backward over the teeth. The turning of theratchet-disk R in the-direction indicated by the arrow .2

is accomplished by the upward and down-' ward movement of the pawl Tdue'to' the rocking movement of the link P on its pivot p, in relationto the arm F, as the latter is oscillated back and forth by the rocker--The pin Z- is adapted to engage with a depression or groove f? in thetop of the projec- 'tion j when the arm F is rocked into its forwardposition, see Fig. 7. The engagement of the pin l -with the groove ftakes lace only when the arm F is disconnected from the clutch-block O,as shown in Fig. That is to say, during the operation of the machine thebridge-member L is in such position that its overhanging portion Z israised free of the projection f on the hub f, as shown by dotted linesin Fig. '3, and consequently the in Z is out of range of the. groove fin t e top of the projection. When the bridge-member L is rocked to stopthe machine its overhanging portion Z is brought down into engagementwith the beveled edge of the projection f, as shown by full lines inFig. 3 and previously described, and the pin Z is carried into positionto engage the groove F. The object of this engagement of the pin Z withthe groove f is to hold the arm F at the forward end of its stroke sothat the traverse-controlling mechanism may be set in its initialposition to start the winding of the bunch as more fully describedhereinafter. It is also to be noted that it is not necessary for the armF to be in its forward position when the portion Z of the member L rocksdownward in order to effect this engagement of the pin Z with the groovef Should the movement of the arm F be arrested in any position otherthan that at the forward end of its stroke the projection f can be swungover under the pin 1 by simply rocking the arm F forward. Such movcmentof the arm is effected manually by pulling the traverse-rod G outwardthrough its bearingin the frame A. It will be observed that the forwardedge of the projection f 'is rounded 0d at f to adapt the pin Z to rideup onto the top of the projection and the inherent spring tendency ofthe pin causes it to drop down into the groove f? when the latter comesinto alinement with the pin.

The operation of the whole machine is as follows: Referring first toFigs. 1 and 2, we have here shown a wooden bobbin :0 of usual formapplied to the winding-spindle B, but other forms of holders for theyarn, such as paper cop-tubes, for instance, might be employedwith'equal efi'ect. Figs. 1 and 2 illustrate the machine at thebeginning of the winding and we have shown the traverse rocker-arm F atthe forward end of its throw. It is obvious, however, that the ma.-chine will not always stop with the arm F in this position, nor is itnecessary, because,

before starting the winding the operator must set the bunch-buildingmechanism and he is instructed to perform the following operations: Thefirst step taken is to pull the traverse-bar C outward in the directionindicated by the arrow 20, see Fig. 1, and if the arm F is in anyotherposition than at the forward end of its stroke it will be movedforward until the pin Z engages the groove f in the projection) of thehub f, This engagement of thepin and groove locks the arm F in itsforward position, as shown in Fig. 1. The operator now pushes thetraverse-bar C backward in the opposite direction and, the 'arm F beingheld from movement, the stud p on the link P is forced down to thebottom of the slot f During the time the machine is operating to windwith the full traverse of the thread-guide the ratchet-disk R remains inthe position illustrated in Fig. 4 with the opening r of the flange r inline with the slot f of the arm F. The pin p on the stud p willtherefore pass through the opening rflwhen the stud is pushed down inthe slot f and lie under the flange 1". At thisv point the pawl T willengage one of the teeth r on the disk R and hold the link P against theaction of the spring 9 in the position illustrated in Fig. 4. Thebunch-building mechanism is now set ready to windthe first layers of thebobbin with a short traverse, and the threadguide G is next adjusted. inits rearward position on the traverse-bar C and the yarn 3/ threadedthrough it with its end secured to the bobbin :1

The operation of the machine is started by turning the handle M which.operates the bridge-member L to release its. lever Z from theclutch-member N, it beingunderstood that the member L is withheld fromaction by suitable detents not here shown.

As the clutch-member N is released it is carried into engagement withthe gear e,

rotation of the gear imparts rotation to the winding-spindle B.Concurrently with the release of the clutch-member N, the projection fis also released from engagement with the member L and the hub f of thearm F slides into position to engage the clutchblock 0, under theinfluence of the spring 0?. As the slot 0 rocks into alinement with thespline f on the hub {i the two are engaged and in this manner t to therocker-shaft D and is oscillated thereby. The stud p is now at thebottom of the slot and the rocking movement of-the arm F is transmittedto the traverse bar C through the link P to impart a relatively shorttraverse to the thread-guide G. The pawl T is now hooked underone of theteeth a on the disk R to hold the end of the link P in its lowermostposition, 'as before described, and the first backward movement of thearm F will cause the link to rock slightly in relation to the arm. Thiscauses the'end of the pawl T to be moved upward around the axis of thedisk R and hence the disk will be rotated to a slight extent by the sotion of the pawl. Fig. 4 illustrates the arm F at the forward end of itsfirst throw while Fig. 5'shows it at the rearward end and it will beseen that in this latt r position the disk R has been turned thro gh adistance equal to the length of one tooth. This brings the end of theflange 1* .over the pin p on the stud 72 sothat the latter is held atthe lower end of the slot f after the pawl T swings away from the teeth1". The upturned lip r on the flange r is provided to insure that thepin 39 will slide easily under the edge of the flange even if there pinp of the operation of the mechanism. At the next forward stroke of thearm-F the pawl T is again engaged with the next tooth on the disk R andupon the rearward movement of the arm the disk is turned again to carrythe rim 1" still farther around on the This action continues until thedisk R has been turned through a complete rotation and the opening 1' isagain brought into alinement with the .slot f on the arm F. Fig. 6illustrates the parts in the position they assume just previous to thecompletion of the rotation of the disk R. The pin 12 is now held justunder the rear edge of the flange r and as the arm F moves backward intothe position illustrated in Fig. 7 the disk It is turned sufiiciently tobring the opening r in line with the pin 12 and the latter is released.The release of the pinp allows the spring 1 to carry the stud p to theupper end of the slot f and henceforth the arm F will act through thelink to impart the full length of throw to the thread-guide. After therelease of the pin 72* the pawl T is carried away from the disk R andhencethe latter is not turned farther, but is held by the pawl S withthe opening r in the flange r in position to admit the pin p when themechanism is reset for winding a new bobbin.

Referring now to Fig. 2, it will be seen that while the stud p is at thebottom of the slot f the arm F will act to reciprocate the thread-guidewith a traverse of about one half the length of the full traverseillustrated by the layer 'y This causes the yarn to build up in therelatively short layersto form the bunch y and the number of layers inthe bunch is determined by the number of oscillations required to turnthe disk .B. through a complete rotation. We

have preferred to show our device arran ed with sixteen teeth on thedisk R, so t at sixteen traverses of, the thread-guide will take placebefore the bunch is completed, but it is obvious that a greater (ir lessnumber of teeth might be provided so that more or less yarn would bewound into the bunch. Furthermore, the ratchet might be made with verymuch' finer 'teeth and means provided to adjust the pawl T to take oneora number of teeth at each movement of the arm F so that the bunchcould be'w ound to contain various lengths of yarn as desired. After thebunch is completed on the bobbin the traverse-mechanism acts toreciprocate the thread-guide with the maximum extent of traverse tobuild the main portion of the bobbin with full length layers as beforedescribed; and after a bobbin is completed the parts of thecontrolling-device are in position to be reset for winding'the bunch onthe next bobbin. The resetting of the device is accomplished with twosimple movementsof the hand, as before explained, and requiresno specialskill or expertness on the part of the operator. Furthermore,the-arrangement is so simple, and the mechanism so positive in action,that the device cannot get out of order and it is practically proofagainst damage through carelessness.

It is obvious that our new device might be applied to machines ofdifferent design from that here shown and described, or 7 adapted forother arrangements of winding mechanism. For instance, the controlling-vdevice for regulating the extent of the traverse with which the yarn iswound might be arranged to operate in connection with atraverse-mechanism for reciprocating the winding-spindle in respect tothe guide instead of reciprocating the uide, itself.

Various modificationsmig t also be made in the form and structure of theparts of our device without departing-from the spirit or scope of theinvention.
